Subject: [IPV6]: Add ndisc_netdev_notifier unregister.
X-Git-Tag: v2.6.19-rc5~19^2~2
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=36f73d0c3b7efa72cd8b89f2d429ff39bc12f15c;p=linux-2.6

[IPV6]: Add ndisc_netdev_notifier unregister.

If inet6_init() fails later than ndisc_init() call, or IPv6 module is
unloaded, ndisc_netdev_notifier call remains in the list and will follows in
oops later.
